Was wondering why you dont see many foundations formed with standard 3/4″ pllywood…I have seen shiplap, and form ply..paperface, but not 3/4 standard? If you are only going to use the ply once for the foundation and then put it on the walls for sheathing is it advisable? Thanks

When I was a kid in Louisville they'd always use the floor sheathing (1x8, IIRC) for forms. Pretty sure I've seen plywood floor sheething used once or twice, but don't recall ever seeing wall sheathing.
However, they don't do many poured foundations around here, so I'm working mostly on distant memories, not current practices.
